Hello I have just joined this site.I have been looking at mods to improve my V3. I use Senn HD 600 at the moment. I am no electrical engineer but my son is and he can do the work for me.I have looked at www.rock-grotto.co.uk/musicalfidelityxcanv3.htm and www.rock-grotto.co.uk/x-can-v3-tweaks.htm I am a little unsure about which one to follow and the exact shopping list for what caps etc. I need qantities etc. It would be great if the authors of these artcles could contact me or if anyone else can help.  |

All the values and voltages are actually printed on the side of the capacitors just open it up and have a look. I will put a parts list together though and should have it up in a few hours.
Mike.

Hi Malcolm, (as per PM) Here's what you need, available from www.rswww.com They only sell in multiples of "5" so I'll tell you how many to order....you'll be left with a couple of spares: 315-0962 x 5 (100uF 63V Pana FC) 315-0782 x 10 (2200uF 35V pana FC) 315-0754 x 5 (1000uF 35V pana FC) 768-497 x 5 (470uF 16V Non polar) 521-3419 x 5 (10uF 63V Non polar) 507-4753 x 5 (heatsinks) That's you ready to roll! All the best. Mike. PS: if you like you can just order 15 of the 2200uF and use them in place of the 1000uF. Whatever you do don't fit higher capacitance in the 100uF slots... they "must" be 100uF. |

Hi
Just read this again
What's the importance of those 100uF being 100uF ?
thanks

What's the importance of those 100uF being 100uF ? The 100uF caps are part of a low-pass filter to remove unwanted hiss and other high-frequency nasties from the audio signal before it is amplified. Because of the nature of capacitors, if you fit lower values the filter frequency increases (smaller caps are better at higher frequencies - big ones can't "keep up"). If you fit higher values, the filter frequency drops and starts to shave treble off your sound. Trust me - I originally put 150uF caps in before I realised they were part of the filter. It was just about listenable, but all the fizz and sparkle from things like cymbals disappears. It's quite a relaxing sound, but you feel like there's something missing. Hope that helps. |

Sorry - I could easily have given you the short, non-patronising version, couldn't I!

Thanks.
I need to understand what function these caps are performing, to decide whether to change or not !
If they are in a power supply then usually ( as long as the ESR is low) , then bigger is better, but if they are performing a filter function, I tend to leave alone, or just replace with one of the same value.
